Patient should be on a stable diet, ideally for two to three weeks prior to collection of blood, and should fast for 12 to 14 hours before collection of the specimen. Stop biotin consumption at least 72 hours prior to the collection.

A CBC is used as broad screening tests to check for such disorders as anemia, infection, and many other diseases. A CBC gives important information about the numbers and kinds of cells in the blood, especially red blood cells, white blood cells, and platelets. A CBC helps your health professional check any symptoms, such as fatigue, weakness, or bruising, that you may have. A CBC also helps your health professional diagnose conditions, such as infection, anemia, and several other disorders.

CMP-14 Includes:

Glucose Test

Blood sugar level, which is the most direct single test to uncover diabetes, and may be used not only to identify diabetes, but also to evaluate how one controls the disease.

Kidney Profile

Bun or Urea Nitrogen BUN is a by-product of protein metabolism eliminated through the kidneys. BUN is an indicator of kidney function. Creatinine, SerumAn indicator of kidney function. Bun/Creatinine RatioCalculated by dividing the BUN by the Creatinine.Glomerular Filtration (eGFR) Provides an assessment of filtering capacity of the kidney.

Fluids & Electrolytes

Sodium One of the major salts in body fluid, sodium is important in the body's water balance and in the electrical activity of nerves and muscles.Potassium Helps to control nerves and muscles.Chloride Similar to sodium, it helps maintain the body's electrolyte balance.Carbon Dioxide, Total Used to detect, evaluate, and monitor electrolyte imbalances.Calcium- A mineral essential for development and maintenance of healthy bones and teeth. Also important for the normal function of muscles, nerves and blood clotting.

Liver panel

Protein, Total Together with albumin, a measure of the state of nutrition in the body.Albumin Serum one of the major proteins in blood and a reflection of general state of nutrition. Globulin, TotalA major group of proteins in blood comprising the infection fighting antibodies.Albumin/Globulin Ratio Calculated by dividing the albumin by the globulin.Bilirubin, Total A chemical involved with liver functions. High concentrations could lead to jaundice.Alkaline Phosphatase A body protein important in diagnosing proper bone functions and liver functions.Aspartate Aminotransferase (AST or SGOT) an enzyme found in skeletal muscle and heart muscle, liver and other organs. Abnormalities could represent liver disease.Alanine Aminotransferase (ALT or SGPT) an enzyme that is found primarily in the liver. Abnormalities could represent liver disease.

Lipid Profile

A Lipid Profile is a basic cholesterol screening with total cholesterol, HDL, LDL, VLDL, Triglycerides and Risk Ratio (Total/HDL).

Prostate Specific Antigen (PSA)

A PSA is a protein produced by the prostate and released into the bloodstream in very small amounts. When there is a problem with the prostate, such as when prostate cancer develops and grows, more and more PSA is released, until it reaches a level where it can be easily detected in the blood. Health professionals must try to both detect prostate cancer and to differentiate between slow-growing cases and prostate cancers that may grow aggressively and spread to other parts of the body (metastasize).

Urinalysis, Complete

A complete urinalysis is useful in the evaluation of conditions such as urinary tract infection, dehydration, and kidney stones.

Testosterone Free (Direct) with Total Testosterone

Testosterone is a steroid hormone (androgen) that is produced by special endocrine tissue (the Leydig cells) in the male testes. Its production is stimulated and controlled by luteinizing hormone (LH), manufactured in the pituitary gland. Testosterone works within a negative feedback mechanism: as testosterone increases, LH decreases, whereas increased LH will cause decreased testosterone. Testosterone levels are diurnal, peaking in the early morning hours (about 4:00 to 8:00 am), with the lowest levels being in the evening (about 4:00 to 8:00 pm). Levels will also increase after exercise, but will decrease with age.About two-thirds of testosterone circulates in the blood that is bound to sex-hormone binding protein and slightly less than one-third bound to albumin. A small percent (about 1-4%) circulates as free testosterone.

Dehydroepiandrosterone sulfate

DHEAS is an androgen, a male sex hormone present in the blood of both men and women. It has a role in developing male secondary sexual characteristics at puberty, and it can be metabolized by the body into more potent androgens, such as testosterone and androstenedione, or can be changed into the female hormone estrogen. DHEAS is produced by the adrenal cortex, which is the outer layer of the adrenal glands, with smaller amounts being produced by the woman's ovaries and man's testes. DHEAS secretion is controlled by the pituitary hormone adrenocorticotropic hormone (ACTH) and other pituitary factors. Since DHEAS is primarily produced by the adrenal glands, it is a useful marker for adrenal function. Adrenal tumors, cancers, and hyperplasia may lead to the overproduction of DHEAS. While elevated levels may not be noticed in adult men, they may lead to amenorrhea and visible symptoms of virilization.

Vitamin D 25-hydroxy

Vitamin D sufficiency, along with diet and exercise, has emerged as one of the most important preventive factors in human health. Hundreds of studies now link vitamin D deficiency with significantly higher rates of many forms of cancer‚ as well as heart disease‚ osteoporosis‚ multiple sclerosis and many other conditions and diseases.

Vitamin D tests are used to determine if bone malformation, bone weakness, or abnormal metabolism of calcium (reflected by abnormal calcium, phosphorus or PTH tests) is occurring as a result of a deficiency or excess of vitamin D. Because vitamin D is a fat-soluble vitamin and is absorbed from the intestine like a fat, vitamin D tests are at times used to monitor individuals with diseases that interfere with fat absorption, such as cystic fibrosis and Crohn's disease, to assure that they have adequate amounts of vitamin D. Vitamin D tests are used to determine effectiveness of treatment when vitamin D, calcium, phosphorus, and/or magnesium supplementation is prescribed as well.
